How do you measure lead density?

To measure the density of lead, you determine its mass and volume, then calculate the density by dividing the mass by the volume.

Steps to Measure Lead Density

Here’s a detailed breakdown of how to measure the density of lead, incorporating the water displacement method as mentioned in the provided reference:

1. Measure the Mass: Use a reliable scale to determine the mass of the lead object. Record this mass in grams (g).

2. Determine the Volume:

   • Water Displacement Method: For irregularly shaped lead objects, use the water displacement method.
     • Fill a graduated cylinder with a known volume of water. Record this initial volume.
     • Carefully submerge the lead object entirely in the water, ensuring no air bubbles are trapped.
     • Record the new water level (final volume).
     • The volume of the lead object is the difference between the final and initial water volumes.
       • Example: If the initial water volume was 50 mL and the final volume was 55 mL, the volume of the lead object is 5 mL.

3. Calculate Density: Use the formula:

   • Density = Mass / Volume

   • Example: If the mass of the lead object is 56.5 grams and its volume is 5 mL, then the density is 56.5 g / 5 mL = 11.3 g/mL

Example Calculation

Measurement	Value
Mass (lead object)	56.5 grams
Initial water volume	50 mL
Final water volume	55 mL
Volume (lead object)	5 mL
Density (lead)	11.3 g/mL

As the provided reference indicates, "the density is the mass divided by the volume of the object." This is the fundamental principle used in measuring the density of lead.
